It would depend upon the circuit of the LCD. I am not familiar with PlatformIO but you program still has #include <LiquidCrystal_I2Cw2.h> and potentially not #include "LiquidCrystal_I2Cw2.h". PlatformIO is complaining that it cannot find...

As Paul mentioned if you have LiquidCrystal_I2Cw2.h in the "Libraries" directory use #include <LiquidCrystal_I2Cw2.h> else if it's in the same directory as your program use #include "LiquidCrystal_I2Cw2.h". If you want the ultimate guarantee use...

I think that in order to fully understand what is going on, you need to get some idea of the interface board circuit. I am pretty sure that R5 and R6 are I2C pull up resistors. We need to determine what J1, J2 and J3 do. Also what is Q1? If we...

OK, lots of things here. If the display is a Buydisplay.com display, and I have no reason to believe that it isn't, 1) If you were to buy the display from Buydisplay.com, you are asked if you want a 5V interface or 3.3V interface. Which version...

... also, what is the motherboard you are using?

Can you tell us the exact display module 6that you are using, so that we may be able to look it up. Someone might even have the display and be able to more easily work out why it is not working.

No problem. I'm glad you found the information you required.

To save others translating there it is:- OK, thank you for your reply. I think I've found it.

The one (library) that I highlighted does.

You could look at this one. Has an ability to choose which wireX to use. Alternatively you could choose a library with a fixed wire and change all entries to wire2 or wire3.

I suggest you look on the manufacturers web site.

Here goes the First Chapter, just dealing with installation. Download Visual Studio Community [VS](free) from here. Install the program..during installation the following screen will appear. I have selected all the items that I require but as a...

Ok, I will try and put something together. It might take a little while, I will have to set up a target system first.

For large projects I use Visual studio, writing to a "Phantom Teensy i.e. simulating the Teensy bits I am interfacing". That way I can single step where necessary and find the problems in my code. I even use it with Nextion code, which is...

Answers 1-No, 2-(1 was a no), 3-YES, 4-probably.

This is w hat we need to see the circuit for. It's quite possible that the ADC has been damaged by input voltage.

If we can see your circuit schematic and/or photo of your layout we may be able to help.

I don't think so, Teensy has it's own library PS2Keyboard.h.

As far as I can see there is nothing about that library that is specific to PJRC or Teensy. Perhaps you should contact the author at paul@pcserviceselectronics.co.uk.

This forum is for Teensy/PJRC products. Perhaps you should ask the question on an ESP32 forum.

Which push button? The only button on the Teensy is a program button.

Since things changed when you changed the hardware it would be useful if you can post your schematic and pictures of your current hardware. Also give any circuit changes between the prototype and the PCB setup.

Pjrc - pretty immediate by my experience.

I have suspected for some time that the only retailer allowed by Sparkfun to sell Teensy products in the UK is, "The Pi Hut". No one else seems to have stock since Sparkfun took over.

The Pi Hut has stock.

When you post code, can you do it between code tags using the </> button. This preserves indenting which makes your code more readable and therefore more likely to get a response. I have posted your code below so you can see the difference. It is...

Yes Teensy is more powerful and more straight forward to use than most but kids don't learn much if you teach them easy stuff.

What about Arduino 1.8.x? It's still on v1.59.

I compressed your code a bit, you seem to be double spacing lines. #include <Arduino.h> #include <AccelStepper.h> #include <string.h> /* The step resolution for all drivers : 6400 step/revolution J1 10:1 J2 25:1 J3 25:1 J4 15:1 J5...

It might help if we could see your code. When you paste it (the code) use the </> button, which ensures that code formatting is maintained.

I think you mean that you are using a radar sensor module that uses a IWR6843AOP. As far as I can see the IWR6843AOP chip has no direct connection to as PC. Perhaps you should state what module you are using.

I know the problem! If it helps anyone during these winter months ( and in my case year wide ), I have been suffering from "Brain Fog". It is/was terrible. I could not work on anything. The problem was very low Vitamin D levels. I now take Vit D...

I can add 20 years to that!

I would suggest you look at the TMP117 for the temperature sensor. Much more accurate and easier to use being I2C. No worries about voltage conversion, noise etc.

The Teensy Micromod has twice the flash of the Teensy 4.1 but a slightly smaller amount of Serial and SPI ports (I think).

When posting code can you paste it between CODE tags using the </> button. It makes it much more likely that you will get an answer to your query as your code is presented in a more understandable mannber. #include <Arduino.h> #include...

Perhaps you should have asked CLAUDE to elucidate.

As @h4yn0nnym0u5e said you need to download and install TeensyDuino in order to program Teensy.

From Kickstarter: Will I be charged more later? That depends. When you redeem your proof of pledge, you may be required to pay applicable sales or value-added tax and/or shipping fees, depending on the reward and where it is being delivered.

I would say that IS the main problem. Teensy is mainly a dev board, but not an ecosystem, like AF Feather or SF Thing Plus. The T3.5/6 ot T4.1 were great for me when I wanted to have a powerful single board MCU with SDIO. Yes, the Teensies have...

Could you show your code using QNEthernet. If you do I am sure Shawn will be in touch.

I suggest you try using QNEthernet. NativeEthernet is NOT actively SUPPORTED by it's author and hasn't been for quite some time, whereas QNEthernet is VERY ACTIVELY SUPPORTED. The Author is often on this forum helping users with their Ethernet code.

Ok, when using the Teensy with an Audio Board like that, it has happened that parts from the underside of the Teensy touch parts of the Audio Board and SHORT OUT. That's one of the reasons why it's better to use tall plug and sockets for the...

A photo showing the Teensy would be useful.
